Hey all; I have to write a report on a certain bus (the bus is associated with a uC), based on a technical document. Thing is, we haven't learned much about buses yet. I understand most of it, but there's one thing I don't understand. What is a slave and what is a master? Here's some phrases from the doc. I think If someone could explain them I'd have alot better handle on buses and the master/slave idea in general. "This register contains the address the IIC Bus will respond to when addressed as a slave." "This would ultimately result in either the current bus master or the IIC Bus module losing arbitration..." (the IIC is the name of the bus) "IAAS — Addressed as a slave bit" "0 = Slave receive, master writing to slave 1 = Slave transmit, master reading from slave" "The first byte of data transfer immediately after the START signal is the slave address transmitted by the master." "Only the slave with a calling address that matches the one transmitted by the master will respond by sending back an acknowledge bit." Thanks.
